What is exterior wall cleaning…
Exterior wall cleaning is one method of regular maintenance to keep the building’s appearance clean and to prolong the life of the exterior materials.
As shown in the photo above, even if the paint film on the exterior wall is in good condition, rain streaks, dark spots, or moss can occur due to sunlight and structure.
When the exterior wall becomes dark or moss grows, the common options are “exterior wall painting” or “high-pressure washing of the exterior wall”.
If it is within reach, such as around the first floor, it may be possible to clean it yourself using a brush or sponge with a household cleaning machine, but it becomes quite difficult for the second or third floors.
Do you have any concerns about dirt on your exterior walls?
“It’s been 5 years since I painted, and while it’s not time for a repaint, I’m concerned about one area that looks dirty…”
“Painting is expensive, so I don’t plan to do it yet, but I want to clean the exterior while keeping costs down…”
“It’s a three-story building, but is it possible to clean without scaffolding…?”
“Will this dirt come off with just cleaning…?”
“I’m worried that the detergent will discolor the exterior walls.”
For those with such concerns, Kakeru Koumuten’s exterior cleaning can solve your problems!
Why is Kakeru Koumuten’s exterior cleaning popular in Musashino City?
We would like to introduce the “7 Points” that make Kakeru Koumuten’s exterior cleaning highly regarded in Musashino City!
Point 1 Overwhelmingly low cost
Typically, exterior painting and high-pressure washing require scaffolding, which inevitably incurs high costs.
Kakeru Koumuten’s exterior cleaning does not require temporary scaffolding, allowing you to restore the beauty of your exterior at about one-tenth the cost of exterior painting!
Point 2 Cleaning without damaging the exterior!
We use gentle water pressure instead of high pressure for cleaning. The brushes used are special brushes that clean gently, removing dirt without damaging the exterior walls.
The detergents used are formulated to prevent discoloration of the sashes and exterior walls!
We also differentiate the detergents used based on the type of dirt, such as rain stains, blackening, and moss!
*Please note that detergents strong against moss can harm or kill plants if they splash on them, so caution is necessary! However, even if we cannot use a moss-resistant detergent, cleaning is still possible, so rest assured!
Point 3 Can clean the exterior without causing much inconvenience to neighbors!
By using a special brush to apply a gentle water flow, it is less likely to splash compared to directly spraying water with a hose!
The detergent used also has little to no odor.
The machine used operates quietly as it is electric.
That said, if the building is close, there may still be some inconvenience, so we will always greet the neighbors before the work begins.
If there are cars nearby, we will protect them with car seat covers!
Point 4 Short construction period!!
For a typical house exterior cleaning, it often can be completed in just one day even for full cleaning!
Since the work is generally done outdoors, cleaning can be done even if you are not home!
Of course, we will take detailed photos of the work and send them to you later.
Point 5 Cleaning of areas other than the exterior is also possible!
In addition to the exterior, we can clean the following areas!
・Exterior structures (blocks and tiles)
・Concrete surfaces (such as parking lots)
・Carports
・Roofs and solar panels (there may be cases where this is not possible)
Please consult us about any other areas of concern!
Point 6 We will conduct a site survey before construction!
Before construction, we will check the condition of the exterior walls and joints and greet the neighbors.
We will confirm on the day of cleaning whether the work can proceed without issues.
Point 7 Estimates can be provided using photos and drawings!
We can communicate via LINE or email, and provide estimates based on photos and drawings (floor plans and elevation drawings)!
In cases where it is difficult to provide an estimate based on photos or drawings, we will visit the site for an inspection.
Estimates will be sent within 1 to 2 business days after receiving the photos or drawings!
What should you be careful about when cleaning exterior walls?
Next, we will explain the “5 points to be cautious about” during exterior wall cleaning!
Caution 1 Severely deteriorated exterior walls
Severely deteriorated siding or mortar walls with many cracks may not be able to be cleaned.
This is to prevent leaks and peeling of the paint film.
Caution 2 Some stains won’t come off…
Stains from years of neglect, such as darkening or rain streaks, may not come off even after cleaning.
In particular, it is difficult to completely remove rain streaks and darkening from textured wall finishes like Jolly Pat.
If you try to forcibly remove darkening or rain streaks from Jolly Pat walls, it may lead to discoloration or damage, so we will use specialized agents to clean gently as much as possible. 
As shown above, even when using specialized chemicals on textured wall finishes like Jolly Pat, some rain streaks may remain, so caution is necessary.
Depending on sunlight and location, it is recommended to clean the walls every 3 to 5 years without leaving dirt!
Caution 3 Severe deterioration of joints
If the joints of the siding exterior are severely deteriorated, it may lead to leaks, and therefore, we may not be able to carry out the work.
Note 4 There may be cases where work cannot be performed due to the structure of the building.
It may be difficult to work in areas such as above eaves, above bay windows, or extremely narrow spots.
We will confirm this during the inspection.
Note 5 We will need to use electricity and water!
During cleaning, we will borrow electricity and water.
If there is no electricity or water outside, additional costs may be incurred, but we can also provide a generator or tank!
